最近項(xiàng)目Android編譯版本改為targetSdkVersion26, 之前隱藏的版本問題暴露出來, 尤其是文件第三方打開及Apk更新問題,這里記錄下7.0以后文件相關(guān)問題
問題描述:
安裝apk的代碼一般寫法如下，網(wǎng)上隨處可以搜到:
public?static?void?installApk(Context?context,?File?file)?{? Intent?intent?=?new?Intent(Intent.ACTION_VIEW);??????Uri?data?=?Uri.fromFile(file);??????intent.setDataAndType(data,?"application/vnd.android.package-archive");??????context.startActivity(intent);??}??
然而，當(dāng)我們?cè)贏ndroid7.0手機(jī)中執(zhí)行時(shí)，會(huì)發(fā)現(xiàn)報(bào)如下錯(cuò)誤日志
